  "account": "The article explores the cost implications of using free tokens for AI batch queues, emphasizing that free tokens do not equate to a Service Level Objective (SLO). The primary focus is on understanding the operations cost of such a setup by measuring token costs and ignoring operations costs. A minimal worker.py script demonstrates a single-threaded worker processing 1,000 requests with a free model endpoint. The worker completes 987 out of 1,000 requests, with an average processing time of 1.234 seconds per request, totaling 1,742 seconds (29 minutes) and incurring a cost of $24.19. The article also discusses the potential impact of fault injection, such as network loss, highlighting the importance of queue age and deadline slack as indicators for actionable control decisions.",
  "summary": "Free Tokens Are Not an SLO: An Ops Cost Drill for AI Batch Queues This week, two numbers trended: a harness at 100%, a model at 30%. For platform teams, a better pair is queue age and deadline slack. This article is a cost drill for the simplest AI batch path: free tokens, free server, non-negotiable deadline. Disclosure: This article was prepared as part of MonkeyCode's product outreach.…",
